Attorney UNITED STATES PATENT OFFICE- JOHN ARNOLD, OF NEWARK, NEWJERSEY.

IMPROVEMENT IN SHUTTER-WORKERS.

Specification forming part of Letters Patent No. 156,524, dated November3, 1874 application filed October 14, 1874.

To all whom it may concern:

Be it known that I, JOHN ARNOLD, of Newark, in the county of Essex andState of New Jersey, have in vented certain new and useful Improvementsin Window-Blind Closers; and I do hereby declare that the following is afull, clear, and exact description thereof, ref erence being bad to theaccompanying drawings, and to the letters of reference marked thereon,which form part of this specification.

My invention relates to the ordinary springhook shutter-fastening; andit consists in the construction and arrangement of a device forreleasing the fastening from the hook in the wall and for closing theshutter, as will be hereinafter more fully set forth.

In order to enable others skilled in the art to which my inventionappertains to make and use the same, I will now proceed to describe itsconstruction and operation, referring to the annexed drawing, in which-Figure l is a perspective view, showing my device attached to a shutter;Fig. 2, a bottomside'up view; Fig. 3, a side elevation, with the sidepiece removed; and Fig. 4, a perspective of the device complete.

A represents a shutter with an ordinary spring-hook fastening, B. Thisfastening is constructed in the usual manner with one hook on each sideof the. shutter. On the inner side of the shutter A is secured a box orcase, 0, having a slot or opening on its under side along the inneredge. D represents an L-shaped lever, the vertical part of which extendsup through the slot or opening mentioned into the box, and is, withinsaid box,

provided with a collar or flange, a, to prevent its coming out. Theupper end of the lever D bears against a shoulder, 12, in the top of thebox. 01 represents a flat spring, one end of which is fastened to thebox and the other end coiled around and fastened to the vertical arm ofthelever D. This lever has two motions: First, it can be drawn straightinward, and, second, it can be thrown outward, on a circle; and fromboth it is thrown back to its original position by the spring d, which,by its peculiar position within the box, as shown, allows of both ofthese movements of the lever. The end of the lever D is formed with ahandle, D, which is bent slightly outward, so as to be easily taken holdof. Theinner hook of the fastening B is, by a rod or wire, h, connectedwith the vertical arm of the lever D immediately below the box or case0.

The operation of this device is as follows:-

The shutter being thrown open and fastened back to the wall, when it isdesired to close the shutter, it is only necessary to take hold of thehandle D and pull the lever D inward, when the fastening is at oncereleased from the hook in the wall, and by continuing to pull on thelever the shutter will commence to turn on its hinges. As the shutterturns the lever must ,be thrown outward, in order to get sufficientleverage to close the shutter. As soon as the pressure is removed fromthe lever the spring 01 at once throws it back to its proper positionagain.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is

The combination of the box or case 0, L- shaped lever D, with handle D,and the spring d, the lever being by a rod or wire h connected with theshutter-fastening B, all constructed and arranged to operatesubstantially as and for the purposes herein set forth.

In testimony that I claim the foregoing as my own I affix my signaturein presence of two witnesses.

JOHN ARNOLD.
